This heavy duty pump motor shaft seal is made with carbon graphite, stainless steel and Viton rubber for extra durability and resistance to chemicals. Especially recommended for use on pool and spa pumps connected to a salt chlorine system or ozonator.
This seal can be used on many different makes and models of pumps which can be seen under the "Parts" tab above. Some of the more common pumps include the Pentair Superflo, Challenger and Pinnacle, the Hayward Max-Flo II, Jacuzzi Cygnet, and Aqua Flo Dominator.
What is the correct shaft seal replacement part for a Hayward Super pump II with a salt system. The service technician will replace all the required O-rings. If I purchase a replacement motor and a new shaft seal, is there anything else that I need to purchase for the tech. (besides O-rings)
What is the difference between a chlorine pool and a soft water with regard to the seal?
Dan, Salt-water is more corrosive to equipment so it is recommended to use a heavy duty shaft seal. Other wise, the seal will fail prematurely and cause damage to the motor.
Which side of the spring loaded piece touches the ceramic disc on the second piece on a ps 3867.?

It will depend on the model of your pump, not your motor. The motor can go to several different model pumps, so would need to know the model of your pump to determine the correct shaft seal.
should I replace the seal every time I replace the motor?
Yes we suggest replacing the shaft seal whenever you replace your motor as the old seal sometimes does not mate up properly with the new motor. Also the warranty on the motor is voided is there is leaking to due the seal.
Why should I purchase the heavy duty seal?
The heavy duty shaft seal features carbon graphite, stainless steel, and Viton rubber. The properties of this seal contribute to the resistance of chemical corrosion. This is the best choice for salt chlorine generators or ozonators.

Existing shaft seal was leaking (salt water pool) and found out my previous repair guy did not put in a heavy duty seal for salt water. Ordered the replacement from INYO and had it here in a couple of days. Disconnected the power from the motor, removed the pump faceplate and housing from the motor. Easily removed the diffuser and impeller following the instructional INYO video and replaced the seal shaft. Put everything back together in reverse order and fixed the leak.

Pros: Excellent Fit
Excellent fit. Better than original spring and materials. Perfect replacement. I did not choose this item, it was suggested by the online chat. Glad they did. Excellent product that fits perfectly. I have a salt system and this one was recommended over the one I asked about. Very happy.

I spoke to a customer service representative and explained what I needed and she told me that I would also need this new seal. I didn't think about this part but she knew I would need it and I did need this when I started replacing my pump motor.
